Application filed September `30, V1925. Serial No;Y 59,550."

Theobject of my iinvention is to provide a tractor control deviceioicsimple, durable andv inexpensive construction, particularlyv intendedand adapted tor vcontrolhuiga Fordson tractor from a binder or otherindependent machine.

With this and other objects in view, my

invention consists in` the construction, ar-

y rangement and combination ofthe various parts o mytractor controldevice, wheres,

-by the objects contemplated areattained, as hereinafter more Jfully set`forth7 pointed out in my claims, and illustrated in the accompanyingdrawings, in which:

Figure 1 shows a side elevation ot my improved tractor control deviceinstalled on aA tractor and binder.

Figure 2 is a side elevationV o 't apart of theA mechanism viewed fromVthe opposite side. A

`Figure 3, is a detail, sectional view taken on the line 3-3 of Figure2.

Figure 4 is a perspective view partk of) the tractor control mechanism.Y

Figure 5 is a sectional view line5-5 of Figure 1; and

taken .on the Figure 6 is a perspective view of the y.

keeper employed withmy control 'mechanism'. Inthe accompanying drawings,I have' used the reference numeral 10 to indicate generally a tractor,preferably of thefFord son type, having the steerable front Wheels 11,the rear traction Wheels 12, the difieren-Y.

tial'ca-sing 13, and the steering mechanism, including the rod 14.

The tractor has alsoithe foot pedal 15 as the binder may be operated byone person. A

My improved control is intended for solving this problem. i y l .c

My device comprises an inverted U-'shaped yoke 20 having t-he arms'21.At theirlower ends, the arms 21 are connected byfa cross rod or shaft 22from which spaced arms 23 are inclined upwardly and forwardly.

The cross rod 22 is arranged just rearwardly of the differential caseand the arms i 23 yare .fastened 'to the differential lcaseY by means ofbolts 24 screwed into the holes found in the regular tractor structure.j

, A rod25 ispivoted to Y,one of the arms 21 in any suitable way as forinstance by bend- P ATENT: oFrIcl-z. i

ingits end .at Vright vangles to its main pory tion and extending thebent end through a hole 26=in such arm 21.V

The forward end of. therod 25 is fastened by a U-bolt 27 `to the rod 14which forms part of the ordinary steering'mechanism voi the Fordsontractor.

`A short post 28 extends ,upwardlyk from the central portion of theyoke20 and has a ball on its upper end. Receiving the ball is a socket28a secured to the end otV the control:

rod member 29. l Y

A second control rod member 3Q isfmount-. ed on the rod 29by'meansofadjustable clamps 31 and 32 and in such manner asto permit therelative f longitudinal adj ustmenty of the rods 29 and'30ffor1actuating the conl trol mechanism for usewith `diil'erent kinds i lofindependent mechanisms.

The rear end of the ro'd 30l is pivoted to a lever 33. .The lever 33 isj pivoted .ons` the :trame ofY the .f binder 17 -Mounted on the4 rameoftherbinder 17 adjacent to the ,leverI j 30 is a-curved bar or thelike34. i

On the lever 33 is anger 35 arranged to engage the curved bar' 34t`orassisting in holding the lever 33 in proper upright posif C0llars36 aretixed tothe rodl 22 outside thefrespective arms 231or preventing anylongitudinal movement ofthe rod 22.7

It willr thus be seen that 'the operator may Vsit on .the yseat 19 andby-manipulating the lever 33 may move the rods30 and 29 'backwardandforward,rthus swinging the yoke 20 and actuating theV rod 25 foroperating the rod -14 of the ksteering-mechanism in the romthe ordinarysteering wheel' 37 `ofthe tractor.`

same Vmanner thatthe rod 14 is 'operated4 It is', likewise embleem the@mail i on the binder-17Ibe able to controltheclutch` and fuelrfeed ofthe tractor. For this pur-. o v.pose j l f Asmall angle bracket 33- isfixed by means Pivote'd I'providethe following means'.

of a bolt'39 to thetractor frame.

to the bracket 3S'is'a-leve`r'40. Fixed to the l lever 40 is a iinger orthe like 41having a' hook-shaped member 42,'which extends overthershank' 15a of the clutch' control'pedal 15, so that lwhen the` lever40.., is pulled rearward 1y, the clutch pedal will be depressed and whenthe lever is permitted to move forwardly, the clutch pedal may rise fromits dotted line position shown in Figure 2 to its full line normalposition shown in said figure.

During such movements, the hook-shaped portion 42 of the finger 41slides ou the shank 15. A spring 43 is connected with thi` lever 40 andthe trame of' the tractor in such manner as to normally tend to draw thelever in .its upright position,` as shown in full lines in Figure 2.

In order that the fuel sup ily may be reduced and the engine throttlecldown when the lever 40 is actuated to throw out the clutch, I providethe following.;r means:

Fixed, on the fuel control rod 16 is a bracket or the like 44, whichnormally stands in horizontal position, as illustrated in Figi-4 ure 3,with its ends projecting laterally from the rod 16.

Mounted on the shank l near the crank portion b thereof is a clampcollar Aiehain or suitable means 46 connects the clamp collar 45 withone end ot the bracket 44. Secured to the inturned end 38 of the bracket3S is a. rod or `the like/47, which is inclined upwardly and isconnected at its upper end with the spring 49 which has a straightenedend "50 extended through the other end of the `bracket `44and1screwthreaded to receive a wing nut 51 by which the tension on thespring49 may be regulated. ,i

The parts are so constructed and arranged and connected that when thelever 40 is in its upper and forward position shown in full lines inFigure 2 for permitting the clutch pedal 15 to stand in position wherethe clutch is engaged, the bracket 44 stands in horizontal position.lVhen the bracket 4iis in this position, the fuel control rod 16 is insuch position that a proper amount of fuel is furnished to theengine foropemting` the tractor under load. y When the lever 40` `is pulledrearwardly and downwardly, as for instance to its dotted line positionshown `in Figure 2, the clutch pedal will be depressed and the clutchthrown out. y

Simultaneously the clamp collar 4.7 and chain 46 will move downwardly,swingingthe left-hand end of thebracket 44 (seeFiaure 3) downwardly andthe right-hand y end thereof upwardly againstfthe tension of the spring49. This movement will impart rotation to the fuel control rod 1,6 forreducingr the amount of fuel supplied to the engine and thus throttlingthe engine down. It is obvious that for adaptation to a tractor, thethrottle rod 16 of which rotates in an opposite direction to that shown,the bracket 44 may be reversed end Ifor end and the clutch pedal l5 whenmoving downward will then rotate the rod 16 in the opposite direction.

in its lower positions. i

It will thus be seen that the operator ot y a machine sitting on thebinder may keep his hand on the lever 33 and by manipulating; itproperly, steer the tractor. j

By pullingi on the rope 53, the operator throws the` tractor out of gearby disengaging the clutch and at the same time rotates the rod 16 forreducing;r the supply of fuel to the engine.

It is thus possible for one manto operate both the binder and thetractor.

Some changes may be made in the details of the construction andarrangement of the"` various arts of my improved tractor con trol. witout departingr from the essential features and purposes ot myinvention,and it is my intention to cover by my claims any modilied forms otstructure or use ofmechanical equivalents, which may be reason ablyincluded within their scope.

I claim as my invention:

1. In a tractor control structure,` a lever adapted to be pivoted to atractor, a finger adapted to slide along the shank of `a clutch controlelement, and means forl yieldinghy tendingr to hold the lever in oneposition of its movement, means for actuating` said `lever in anotherdirection from an inde rendent mechanism, a bracket adapted to be limeans for connecting one of said ends with such clutch control member ofthe tractor,` and a yielding device for connecting' the other of saidends with the tractor trame.

' astcned to a fuel control rod having projectnu,r ends,

1in y 2. In a tractor control structure, comprising a lever adapted tobe pivoted thereto, a finger adapted to slide alongr the shank ol' y a.clutch control element of the ftractor, means for yieldingly tendingr`to hold fthe lever in one position ot its movement, means foractuatinfr said lever in another direction from an independentmechanism, a` bracket adapted to be fastened. to the fuel control rod ofthe tractor, means 'For .zonnccting said brackets with such clutchcontrol inember of the tractor, and a yielding' device 'lor connecting,rsaidV bracket with thc tractor frame for constrainingP the brackettoward` movement in one direction.
